Kenney Westerhof closed MNG-1012:
---------------------------------

    Resolution: Won't Fix

[copied more or less from a mail to the user-list]

The artifactId, groupId and version are mandatory in a <parent> element.

POMs should be able to be used stand-alone. A client that uses your pom
wouldn't know where to look for that parent pom, since the directory
structure on ibiblio is not quite the same as the project tree structure.

Before this attribute was in, m2 always checked ../pom.xml to see if it
matched the declared parent. If so, it used that (and the data in
target/*) instead of going to your local/remote repositories for the pom.
This attribute is just an extension to that, so you can specify
other locations for your parent project than ../. 

It is not and will not be a replacement for <extends> in maven1.

> <parent> with only <relativePath> doesn't work

> Use the following in child pom.xml
>   <parent>
>     <relativePath>../pom.xml</relativePath>
>   </parent>  
> Got error: 
> [INFO] Reason: Missing groupId element from parent element
> Why do we need groupId, artifactId, and version? These data are already contained in ../pom.xml.  It should work the same as Maven 1.0 <extends>.
